On October 5, 2015, we entered into a private transaction with a note holder to purchase $81.0 million of aggregate principal amount of our 3.50% convertible subordinated notes due November 15, 2015 ("3.50% notes") for $82.4 million, which included $1.1 million of accrued interest. In connection with this transaction, we recorded a loss on debt extinguishment of $0.4 million comprised of a loss of $0.3 million from the notes purchased and $0.1 million of unamortized debt issuance costs related to the purchased notes. We used a combination of $66.1 million of proceeds from our credit agreement with Wells Fargo ("WF credit agreement") and $16.3 million of restricted cash to fund the purchase and pay the accrued interest. On November 15, 2015, we paid and purchased the remaining $2.8 million 3.50% notes and funded this payment using proceeds from the WF credit agreement.
On August 7, 2015, the WF credit agreement was amended to modify the maturity date, increase the amount of foreign accounts receivable and intellectual property assets included in our borrowing base and add an additional liquidity covenant.
Under the WF credit agreement, we have the ability to borrow the lesser of $75 million or the amount of the monthly borrowing base under a senior secured revolving credit facility, which matures March 29, 2017. As of December 31, 2015, we had a $68.9 million outstanding balance on the line of credit at a weighted average interest rate of 3.24%. In addition, we have letters of credit totaling $1.0 million, reducing the amount available to borrow to $5.1 million at December 31, 2015. Quarterly, we are required to pay a 0.375% commitment fee on undrawn amounts under the revolving credit facility. As of December 31, 2015, and during the third quarter and first nine months of fiscal 2016, we were in compliance with all covenants.
The WF credit agreement contains financial covenants and customary events of default for such securities, including cross-payment default and cross-acceleration to other material indebtedness for borrowed money which require notice from the trustee or holders of at least 25% of the notes and are subject to a cure period upon receipt of such notice. Average liquidity must exceed $15 million each month, and at all times we must maintain minimum liquidity of $10 million, at least $5 million of which must be excess availability under the WF revolving credit facility. The fixed charge coverage ratio is required to be greater than 1.2 for the 12 month period ending on the last day of any month in which the covenant is applicable. This covenant is applicable only in months in which borrowings exceed $5 million at any time during the month. To avoid triggering mandatory field audits and Wells Fargo controlling our cash receipts, we must maintain liquidity of at least $20 million at all times. The fixed charge coverage ratio, average liquidity, liquidity and excess availability are each defined in the WF credit agreement and/or amendments thereto. Certain schedules in the compliance certificate must be filed monthly if borrowings exceed $5 million; otherwise they are to be filed quarterly.
